**The awesomest formula of them all.**

After four years in aerospace engineering school, one as a math major, 1.5 as a working engineer, five as a helicopter pilot, and 1.5 (and counting) as a computer science graduate student, I know a **lot** of mathematical formulas. But what, you may be asking, *what* is the awesomest formula of them all? I humbly submit to you that it’s this one:

*e ^{iπ}* = -1

How can this be so amazing? Think about it for a second: *e* is the base of the natural logarithm, an irrational number, approximately 2.718. *i* is the square root of -1, a number which is so mindbendingly impossible (since you can’t take the square root of a negative number) it forms the basis for a class of numbers that are called *imaginary* numbers. π is the ratio of a circle’s circumference to its diameter, another (and perhaps the most famous) irrational number, at approximately 3.14159. So. Take *e*, raise it to the power of *i* times π, and what do you get? *-1*. One of the most boringly normal numbers out there. And, oh yeah: no matter to what number you raise a positive number (like *e*), *you cannot get a negative number*.

Like -1.

Awesome, huh?
